How
the System
Works
Unless disabled, the URPA will turn on automatically
when the shift lever is moved into REVERSE (R).
When the system turns on, the three lights on the
display will illuminate for one and a half seconds to let
you know that the system is working. If your vehicle
is moving in REVERSE (R) at a speed greater
than
3
mph
(5
km/h), the red light will flash to remind
you that the system does not work at speed greater than
3
mph
(5
km/h).
If an object is detected at a REVERSE (R) speed of
less than
3
mph (5 km/h), one of the following will occur:

When the System
Does
Not
Seem
to
Work Properly
The light may flash red when the vehicle
is
in
REVERSE (R)
if
the ultrasonic sensors are not kept
clean.
So
be sure to keep your rear bumper free
of
mud,
dirt, snow, ice and slush. Other conditions that may
affect system performance include things like the
vibrations from a jackhammer or the compression of
air brakes on a very large truck. If after cleaning
the rear bumper and then driving forward at least
15 mph
(25
km/h), the display continues to flash red,
see your dealer.
If a trailer was attached to your vehicle, or a bicycle or
an object was on the back of, or hanging out of your
liftgate during your last drive cycle, the light may
also flash red. The light will continue to flash whenever
in REVERSE (R) until your vehicle is driven forward
at least 15 mph (25 km/h) without any obstructions
behind the vehicle.

URPA cannot detect objects that are above liftgate level.
In
order for the rear sensors to recognize an object,
it must be within detection range behind the vehicle.
